The Daytona Beach News-Journal reports a similar 3.7-magnitude "earthquake" on June 10 off of Ormond-by-the-Sea happened about the same time the Navy reported conducting a shock trial on the USS Jackson for testing. The Navy notified the National Oceanic and Atmospheric Administration's National Marine Fisheries Service that another shock trial would be conducted between July 16 and July 20.

The Navy's Sea System Command spokesman Dale Eng said the Navy is working on a statement to release this week.
